Fig.1 Experiment set-up Design of experiments The single factor method was used to conduct the experiment.
The data underlined are single factor parameters.
It is acknowledged that the cutting depth is main factor affecting the cutting force.

The feasibility of the process and the most important process factor which affects the depth of the micro-dimple were investigated by orthogonal experiments.
Electrolyte concentration was the most important factor that affected the depth of the micro-dimple in the selected process parameters.
Comparatively, micro-dimple surface textures have been paid more attention because of their good machinability and excellent tribological properties[4].
In this study, we proposed a modifed TMEMM process with flexible porous material filled in the interelectrode gap and then investigated its feasibility and process affecting factors.
The designed factors and levels based on the orthogonal experiment method were shown in Table 2.

As to the relationship between fluidity of concrete and that of paste, future research can be conducted in two aspects, i.e. one is the influence of the quantity of paste in concrete, and another is the influence of fluidity of paste affected by a couple of factors.
Introduction Compared with other properties of concrete such as mechanical properties and durability, workability is measured by using test methods rather empirical, which usually lack enough scientific foundations.
Thixotropy of plain concrete and fiber concrete is caused by chemical and physical factors.
Reuse of local sand: effect of limestone filler proportion on the rheological and mechanical properties of different sand concretes.
Effect of the addition of ultrafine cement and short fiber reinforcement on shrinkage, rheological and mechanical properties of Portland cement pastes.

The cell assembly technology skillfully combined with the sol/gel transition mechanism about chemical and physical crosslink of gelatin-based hydrogels, in consideration of the main forming factors, through controlling the extruded materials rheological properties and optimizing the forming process, thereby achieved a promising assembling process with high cell survival rate and its corresponding biological viability.
In the sol state, they can be crosslinked into a gel by changing or adding some exterior factors (i.e., temperature, ultraviolet, chemical agent).
Compare to the physically crosslinked gels, the chemically crosslinked gels usually provide a more stable physical/chemical performance with better mechanical properties because of their stronger bonds [18].
Gelatin, a degradation product of collagen, exhibits reversible thermosensitive gelation properties and can be irreversibly crosslinked with glutaraldehyde.
The main factors affecting this process are gelation time and conglutinate property.

The mechanical properties are strongly influenced by the shell / core microstructure.
Mechanical Properties of the Nano / Meso Hybrid Microstructure Compacts.
Such mechanical properties strongly depend on the hybrid microstructure shown in Figs. 3 and 4.
Fig. 7 Relation between the mechanical properties and the microstructural factors such as shell fraction (S) and core grain size (dcore ), in the SUS316L HRS compacts.
Thus, the nano / meso hybrid microstructure material is an effective for improving mechanical properties.

An experimental study of the physical and mechanical properties of untreated and acetylated wood was conducted.
Moisture and temperature are one of the most important factors that lead to the accelerated destruction of wood.
To extend the life of wooden structures, they need protection from adverse factors.
The modification makes it possible to increase the operational parameters of wood by affecting its water resistance, resistance to high and low temperatures, resistance to biological factors and mechanical loads.
Thus, the effect of acetylation on the improvement of some physical and mechanical properties of wood has been established.

The authors concluded that the proportion of 25% of coffee husk presented satisfactory results for physical and mechanical properties, and the increase in the percentage of adhesive had a direct influence on their performance.
The particleboards production with coffee husk and the results indicated that the addition of up to 50% of the husk provides satisfactory results of physical and mechanical properties [10].

The primary cause of aging on silicone rubber is oxygen, light, heat, ozone or other factors conditions.
The study on effect of aging on mechanical and electrical properties is still lesser.
Results and discussion Mechanical properties Table 1.
The mechanical properties of the five kinds of conductive silicone rubber after hot air aging treatment Table 1 shows the mechanical properties of five kinds of conductive silicone rubber samples before hot air aging.
Both the two changes reduce the mechanical properties of rubber significantly.

The landform, climate and groundwater and other factors have significant influence on the formation of saline soil.
Climate Climate is one of the main factors influenced soil salinization, because it directly affects the soil salt movement station.
Mechanical Property Shear Strength Saline soil shear strength affect by the mineral composition of soil, particle size distribution, natural moisture content, compactness and natural structure state, closely related to the salt content. saline soil shear strength - salt content refer with Fig. 2.
Terrain, limate and other factors of Bohai west coast have important effects on the saline soil formation.
The soluble salt content have a greater impact on soil physical properties and mechanical properties, at the same time ,saline soil is the special soil, Under the influence of temperature and moisture, soil salts especially soluble crystalline salt will change, so that the engineering properties of saline soil is very unstable.
